Look in their store and you will find a slightly larger but still very compact version in the 1.5" width. But also sold out for now.
If the 1" version is used in urban environments it seems highly unlikely that a situation would arise where the patient is unable to obtain proper medical treatment within a reasonable amount of time, versus the hours and hours that could pass in a battlefield situation... The extra width to help prevent tissue damage is probably not so much of an issue around modern civilization.
